The Medical College Admission Test (MCAT) is administered by the Association of American Medical Colleges. Since 2007, the exam has become computer-based and is given 24 times a year. The MCAT is an entrance exam for prospective medical students in the United States and Canada.
Section breakdown:
  • Physical Sciences (PS)
  • Verbal Reasoning (VR)
  • Writing Sample (WS)
  • Biological Sciences (BS)
IMPORTANT: "The Writing Sample section will be removed from the current MCAT in 2013. If you plan to take the MCAT in 2013 or 2014, the current exam will be modified and the Writing Sample section will no longer be part of the exam. In its place, a voluntary, unscored trial section will be added starting in January 2013."
In 2010, 82,004 students took the MCAT exam internationally. The mean score 25.0 with a standard deviation of 6.4. The highest possible score is 45.

This free practice test is a pre-exam refresher featuring 261 realistic questions in biology and chemistry for the MCAT. Additionally, it is a worthwhile study guide for any medical type exam requiring biology and chemistry knowledge at the 101 and 201 levels.
